The missing measurement of this right triangle is x=2√14
(a) System of equations: and
(b) One soda costs
(c) One taco costs
<u>SOLUTION:</u>
Given, Mrs. Galicia bought 3 tacos and 2 sodas and paid .
The next day she went back and bought 5 tacos and 1 soda and paid .
Let the cost of 1 tacos be m, and cost of 1 soda be n.
Now, We have to find
(a) System of equations:
3 tacos and 2 sodas cost
5 tacos and 1 soda cost
System of equations are
Now,
So, substitute n in (1)
(b) cost of one soda
(c) cost of one taco
The answer is 1.
When you are solving any equation no matter what the base is (in this case it is 3), if the answer is 0, than we are looking for 1. This is because a log is showing that the base (3) raised to the answer (0) is equal to the number (the x you forgot to put in the equation. If we show that algebraically we get:
3^0 = x
And anything raised to the 0th power is 1.
